Honestly, with the pet changes stealthed in with echo pierce changes, I don't know where to put them for sieges. Tamers are really scary now. I went and fought a few tamers last night. It was crazy. Getting my hp torn up while they were cc'd wasn't fun. Even Void Lightning hurts now. They can jump into groups and just void cancel, letting their pets do work once their ap is high enough. I would go far enough to say that despite where I rank people in my own tier list, they're all viable in every pvp mode. They play different roles and aren't going to perform the same as other classes. With that said, some classes are overall just way too strong in sieges with the right set up. Some classes go from being really poor to having decent performance like say Ninja swapping to a more evasion style build will perform a lot better in large skirmishes because it replaces the defense in his kit and gives him more saving grace. With the pet changes, I would say Tamer is much better suited for backlining than Ninja now just because of her brute force. But Ninja will still be better for cannons and for attacking objectives because of stealth.
